I Taall concern: A Be it known't at` I, BENJaMiN'M. Das

Janome, a citizen of the United States, re V West Hartford, in the county off Hart ordandState of Connecticut, have'in` sidi at vented a newand useful Type-Writer Adding-Machine, of 4which the following is a specification.

This invention relates'to computing ma.

chilies, and is especially adapted to be used f in combined typewriting and computing niachines. yThe invention is` shown herein as applied toa Remington typewriting machine o the basket type in which as usual, the al? phabet and numeral keys operate type. Said' typewriting machine, as usual, comprises a .traveling carriage controlled .by an escapement operated bj said keys, and said carriage may b e positioned by means pf tabulating keys of the usual type.; said tabulating keys preferabl forming part of a decimal tabulator. T e computing machine in one of its broadest aspects belongs to the type of machines known as item4 register machin, in which machines-numbers are temporarily recorded, and laterI carried into the computing wheels proper by the operation of a general operator, or some equivalent device.

Accordi to one as ect of the present invention, as erein disc osed, said'item register comprises a series ofarrays of settable pins; there bein an ai'rayof such pins for each column in w ich a igureis written. -Said pi-ns in all said arrays, when taken together, may betermed a nest, which nest is normally in an ineffective osition, so that the numeral keys operate idly with reference thereto.

Said nest, however, may moved into eective position by the operation of any tabu` lating ke in the column in which computing is to be one. tion, said nest is carried along by thetypewriter carriage by means of an arm fast on said .carriage hus said nest will move step by st ep with the typewriter carria e until a numeral key writes a figure in tiie units place.- When a numeral key rises after writing a figure in said units place, the typewritergcarria'ge, in the usual form of escapement mechanism, moves lalong one letterspace, and in so moving, moves the .pin nest to an 'ineiiectiveposition and disconnects time after a number When in said effective pos- 4parts broken away.

the preferred form of device, as herein/66 i shown the typewriter carriage Vmay then feed along normally without any further effecten the computinxgechanism. At any .thus been written in the units place, the numbers recorded in said pin nest may be carried into aV g of computing wheels and there recorde while -at the same time A'the pins whichl have been set are restored to their normal position, thus putting said nest incondition to have another number recorded therein.

In thus carrying numbers recorded in said' pin nest Ninto the computing wheels, Asaid e computing wheels are arranged to siinulta neoiusly operate a carry-over mechanism. To attain this and other results, the numbers recorded inthe item' .register oi'- -pinnest are not directly carried into the computing wheels, but said of feelers which etermne hoiw` far a set of intermediate wheels 'shall turn, and when said intermediatewheels have thus been turned they are' brought into engagement with the -computing wheels proper, ,and then in being restored to zero, turn said computing wheels'tothe extent said intermediate wheels were permitted to be turned by said feelers. Wherever a carry-over is to be made,- said intermediate wheels turn one digit space farther, thus-turning the eomputin wheels proper one space artller, and erefore registering a carry-over in said computing wheels. A

The computin mechanism may likewise comprise means or rapidly setting the comin nest controls an array puting wheels properto zero, thus setting and the upperv supporting plate shown in section. i Fig. 3 is a right elevation vrith minor Fig. 3*'is a .sectional the typewriterfescapement an`d tabulator.

they have partly o erated. 4. In the ordinar Femingt'on basket type of liine, numeral and alphabet ys 75 are mounted on key levers .162, which,I -when depressed by" means of links 200, swing typears carrying type 76 upwardlyto vstrike against the yunder side of a platen 201.1-HSaid platen' forms part of the usual'ty'pewriter vcarriage' 202, which is drawn vforward in letterfeeding direction by means 'of =afsprin -barrel `(not shown herein),and"is contro led by means of an escapement mechanism ofthe usual kind. Said escapenent mechanism comprisesan escapement wheel77 ha fast to the axle thereof a pinion 203 workin in a rack 204 on the t pewriter carriage, w ilethe escapement wheel 7.7 is controlled'by means of dogs 205 which are vibrated at each depression of a 'keylever 162* by means of a universal bar 206 Ain the usual manner.

'. Said typewriter carriage 202 comprises a rack bar 2 07,o r.-wh1cli may be set stops 208 adapted toy J'coperate with key-operated counter-stopsV 79 in the usual manner; said counter-stops beinginl the form of upstand- .erspective view, largely ing levers` t0 whichare pivoted at their lower lendsforwardlyextending key rods 78 having finger-pieces on the front thereof. Said' counterstops 79 are spaced at letterspace intervals, and, as will be seen from Fig. 1, a scale bar 209 shows in what denominationin a given column the stop controlled by each key will arrest said carriage.

The parts so far described form the usualv parts ofthe standard Remington machine.

To' use said machine for computing, it is provided with a pin nest 133 in which pins are set (viz. depressed) by the various numeral keys as they are operated in predetermined columns, andthe'vnumbers represented by thepins so sety are later carried into computin wheels 114 in a manner hereinafter descried. Said computingl wheels 114 bear-numerals 114 in the broad Hat spaces 114b between their teeth. For thus registering numbers, the pin nest includes a series'of settable pins 113, there being nine plus in each array, so that pinsin each array represent the numbers fromV 0 up to and including 8 in a given column. These pins 113 are held between partition ,plates 138 extending across said pinnest so that all the 0 pins are infront of the first partition plate;` all the 1 pins are between the first and second partition plate, etc.

iso

Said pins are set by being depressed in a manner hereinafter described by the varlous numerals, and said pins are frictionally held either in their normal or their set position by means of ,springs 137, there being one spring for each row ofv pins between every two partition plates (see Fig. 7)'. V

The pins on one array are separated from those on the next by 'means oftlivision plates 136 which are adapted to be slipped in between the partit-ion plates 138, and comprise shoulders 131 and 132 which prevent the di "ision plates from slipping out from-between the partition plates. Thus itwill be seen that each spring 137 presses a' row of alten nated pins and plates.- Each pin 113 com* prises a top' shoulder 134 and a bottom shoulder 135, which shoulders are so spaced -as to allow some play up and down between the partition plates, but at the same time prevent the pins from slipping from between the plates.

4Said pin nest 133 is normally in an inef fective position. When, however, a tabulating key 78 is operated, the counter-stop operated thereby is arranged to move said pin nest into effective position. For this purpose, the counter-stops 79 are arranged to strike a universal bar 8() on their forward stroke, as seen in Fig. 21, which universal bar 80, by means of a bell crank arm 80l fast to the axle thereof through a link 80", rocks a walking beam 158 so as' to press downwardly therear end of a lever 158 pivoted at 158* and extending forwardly to the computing device, so that the front end of said lever will ri'se and lift a pillar 141 by apin 141", which pillar supports the sliding pin nest 133 by means of a frame 140. Said pillar 141 is guided in a fixed slide 234, and to- ,.ther with said frame 140 and in nest 133, 1s supported (Figs. 13, 21 an 22) in its raised position by means of a pawl 144 which a spring 147 (Figs. 4 and 16)- causes to catch under atooth or ledge 143 near the lower end of said pillar. In this raised position of the pillar 141 and pin nest 133, a` rack 148 connected to the pin nest 133 normally engages a blade 154 on an arm 153 extending forwardly from the typewriter carriage, as seen in Fig. 3, (see also the top of Figs. 14, 15, 18 and 21) Said rack 148 therefore carries the pin nest 133 along the frame 140 as the typewriter carriage is drawn along in letterceding direction. The tooth of the rack 148 engaged by the blade 154 deter -mines'in what denomination computing will begin. To enable the pin nest 133 to slide, it has (Figs. 3 and 14) the edges 232 of its frame formed as slides which travel in ways 233m the frame 140. IIn being thus drawn along, the array of Ems on Vsaid rack are successively broug t under a row of fingers 163 which (see Figs. 3, 17, 18, 2l and 22) pro;

ject ldownwardly toward said `pins through openings 210 i'n the4 frame 140, each of said fingers 1,63 .bein attached to a numerallki by means of a ownwardly extending 162, (Figs' 18, 19, 22 and 23) with the result that whenever a numeral key is depressed,l

its finger 163 (as seen in Fig. 22)- will move downwardly a pinl 113, as shown -by the arrow in salid figure. For reasons hereafter described, the 50 key sets pins 113, butthe 9 n0 Pin, and S0 Operates IO.

finger 163.

As a numeral key the' typewritercarrage will berfed foi-wml by means of the f escapement mechanism andthe 'arm 153 onV said carriage will draw alng'the p in nest 133, thus,l bringing another array of pins under the openings 210 so that any numeral key now depreed will set a .pin 113 in theV next array in saidnest. A

When a numeral key has been depressed to record numbers in each array until lthe units array of pins in said nest is reached, the risingr ofthe key will, as in the ease ,of the other-arrays, cause -said pin nest and typewriter carriage yto `feed forward one letter-space, but in feeding forward from Vthe units column, the blade'154, which has been described as fast on the typewriter carriage, strikes the extension'll; of a rock m1114159,

which arm forms part of a, vertical `shaft 160 (see F igs. 3, 15, 16, 17` and 31), .said shaft being connected at its lower end to the pillar supporting pawl 144, so that the swinging of the shaft 160 will swing the pawl 144 clear l of the first ledge 143 Von the pillar 141 andl allow said pillar to drop until said pawl catches .the ledge 142 `on said pillar, thus carrying down the pin nest 133-and with itA been state are turned4 by means of` inter mediate wheels 100, said intermediate Wheels being first turned toan extent determined by the pins set insaid pin nest, and then after being engaged with .the Cmputing wheels proper, saiid intermediate ,wheels are turnedV back to zero, thereby carrying the numbers recorded in tliem into the oomputnggvheels roper. ForV 4turning the intermediate rions' pins' set, there is provided a, general operator or adding key 164 on a. lever 165 'pivoted o nvthe frame,'which key normally stands `in its uppermost positionand is man- 125. .wheels to ,an ext'ent determined bytheva-` i u-ally depressed Awheels and al was written inthe units column, the pinnest ped clear of the blade 154.`

Said arms 104 at their bases, `as best seen in Figs. 2 and 34, are spaced apart the same distance as' the intermediate wheels 100, so that extension dogs 106 on said arms (whose purpose is hereinafter described) will lie between said intermediate wheels,

but at their upper ends, 'at the lingers 112,

Saidarms 107 are journaled on shaft 108 and are normally held in the forward posi-A tion (seen in Fig. 3) by means of a trans-l verse swinging rod 111 fast on rock arms 110, 110 near the base of Said arms. This rod 111 (see'Figs. 14 and 19) at the depression of the adding key 164 is moved clear of the arms 107, thus permitting each spring 109 to draw its arm 107 rearwardly until arrested, as above described, by its depressed pin 113.

which said arms 107 allow said intermediate wheels 100 to be turned. To bring about this result, as the addingkey lever 165- desccnds, a rack 169 fast thereon (Fig. 14) engages a pinion 170 fast on the shaft 101 on which the intermediate Wheels 100 are jour` naled. The"intermediate Wheels 100, while.

As seen in'Fig. 6, each plate 99 lies against a thinweb forming the hub of its computing wheel, and the periphery of each computing wheel is broad so that the washers 98 and plates 99 are behind said periphery. Normally said intermediate wheels 100 therefore intermediate wheel 100 has fast thereon a stepped plate 104, which plate, by coperating with its arm 107 is'adapted to arrest its intermediate wheel as said shaft 101 tends to turn said wheel. The means for thus arresting said plate 104 and wheel 100, comprise a series of steps 105 on the plate 104, said steps being nine in number. Said steps are arranged to coperate with extensions 106 reaching from the arms 107 between the wheels 100, so that if a finger 112 is held against moving rearwardly whenthe adding key 164 is operated, its. extension 106 will prevent its plate- 104 from turning at all, and therefore will prevent`the intermediate wheel -belongin .to said plate 104from turning. This is est shown in full lines in Fig. 19, as viewed in If, however, the finger 112 moves backward as the farther finger in said Fig. 19 is shown as doing, then the extension 106 on saidi finger willg permit the stepped plate'104 to turn until thereon strikes its extension 106 and is arthe rear finger-112 is thus arrested at the point at which it will record 6 in its inter lVhen the addingf key is thus depressed to its full extent', the numbers registered in the at 103 on the intermediate wheels through the sight-opening 240 in 'the cover plate 241 which is fast to the'frame of the machine. Said numbers, as shown in Figs. 2, 14 and 15, are on the broad ends o f the teeth 102 of the wheels 100.

In this connection it should be noted that when the front pin 113 is depressed in any array in the pin nest 133, said pin will record 0, :While -if no any array, the ingerg112 of that array will swin rearwardly until it strikes a stop bar 139 see Figs. 14 and 34) extending entirely across the pin nest 133, and when against sai'dbar 139, the number 9 will be recorded cause in said position the extension 106 of said finger 107 will permit its intermediate -a step 105 pin is depressed in pins 113 will bedisplayed wheel to make nearly a full revolution and "1, ,ses

o far'the action of the a ding key 164 has been described yin its'movement' of -depression, and. said movement has been with 4out eifect on the computing wheels-pro er 114.l As said adding key 164 -approac es `the bottom of its stroke, its key lever 165 strikes an arm 1.77 of a depending link 174, which link is pivotally attached at 175 to the arms 173, 173, on'which the com' uting wheels 114 are carried by means of t eir shaft `116; said arms 173, 1'73` being fast to a shaft 172 journaled on the frame. Thus, as said addingV key approaches the bottom of its stroke (see Flg. 14), it positively moves said computing wheels 114 into mesh with the intermediate wheels 100, which intermediate wheels have just been rotated to an extent determined by the pins 1,13 of the pin nest 133.

Said computing wheelsl have hitherto positively held out of mesh with Said intermediate wheels 100. They were so held by means of 'a four-motiondevice 181-com ris` ing cams 213, 215 on the adding key ever 165. ,These cams enga a pin 180 fast on a bell crank larm.179 rmlng part of the frame"171 which includes the arm 173 and the shaft 116 on which the computing wheels properare journaled. Said pin 180 normally occupies the-position seen in Fig. 3 in" the front cam 213,'and during the depression of said key lever 165, said pin 180 rides in .said l forward cam (Fig. 26),

. lwhich cam is struck from the shaft 166 of of the link 174, as seen in Fig. 26, it swingsposition where it will be engaged by thel rear cam 215 of said four-motion device 181,

thekey lever 165 as a center, and so holds said computing wheels in their u per .posif tion clear' of the intermediate w eels 100. When said adding key lever 165 draws down the computing wheels proper 114 by means the pin 180 past the end of the cam 213, so that it catches behind a latch 214, as seen in Fig. 26, thus locking said -arm'179 into and thus said pin 180"will lock said computing wheels 114 in mesh with the intermediate wheels 100. y

.Said latch 214 is held in position by means of a spring 216, so that the pin 180 cannot escape past it. The cam 215 is struck from shaft 166 as a center, and so holds the computing wheels 114 (Fig. 18) in mesh with the'intermediate wheels throughout lthe ulpstroke of the adding key lever 165. At t end of the up-stnoke, said adding key lever brings its lug 178 against the arm176 of the link 174, thus raising the computing. wheels 114 clear of the intermediate wheels 100.

and at the same time swinging the crank arm 179 to its normal position, as seen in Fig. 3, where it is held y means of a latch latch 217 being held in position by means of are so. curved at their ends that they form on its upward i ackwardlyl turning takes place while the computingV wheels 114 are in meshV with said intermediate wheels, the turning of ysaid intermediat'e wheels rotates the computing wheels" so as to carryl into said computing. wheels the number w ich has been transferred from the in nest 133 to the intermediate wheels.

e washers 98 and plates .99, itwill be remembered, are fast on the shaft 101, and means are lprovided for 'causing 4 said plates to positive y turnthe intermediate wheels to the extent determined by the Vext/ensions 106, and then to turn 4idly. To thus positive] turnits intermediate wheel, each plate 99 `as a lug .129 thereon (Figs. 12, 29 and 35) which lies. (Figs. 31 and 35) i the normal path of a pawl`126, which'pawl is 'pivoted .at 127 on, itsintennediate wheel 100. Said pawl is 4:formally heldin the path of said lug 129- by means of a carry-overV plate 120, the surface of said carry-over plate, as best shown in Fig. 35, forming a cam surface on whichla pin 128 fast on the tail of said pawl 126 rides. Thus, so long as the periphery of said'carrypver plate 120 holds the pawl"126 in the path of the lu'g 129, said lug will drive said intermediate wheel by means of the pivot 127 on which 4its awl 126 swings. Each lug 129 may be e a little lthinner than the lug of lower denomination, as at Fig. 29, to give clearance for the proper engagement of pawl 4126 therewith. 4 Q.

Said pawl 126 is .posltively moved to ineffective position outof the path of the lug 129 when a` number is completely carried into the computing wheel114 engaged by its intermediate wheel 100. Said pawl is. thus moved to ineffective position when (Fig. 33) the intermediate wheel 100 has been turned until the zero on its periphery is at the sight-opening 240. At this time, pin 12R moves said pawl out of the path of the lug 129 because the pin 128 rides down on an incline 124 forming a cam extension of the 'periphery of said carry-over plate 120, thus swinging the tail of said pawl to the point seen in Figs. 32 and 33, where the lug 129 will move idly-past said pawl. Said pin 128 is forcedV down said cam 124 by means of V-over platesbecause theycontrol the carryhe engaged by disk 117 when the-latter dro s to the position-seen at Fig. 33, whereby t e tooth 118 is enabled to set the plate 120 to carry-over positionl The plates 120 have been called carrying-over operation to t computing'wheel next higher in denomination whenever a computing Wheel brings its zero to its sightopening. Each of said carr -over plates is'4 held against rotation by a pleite ,or disk 117 fast on the computing whee'l 11,4 next lower in denomination.; For thispu ose the extension 122 of-.each carry-over p ateformsfa f Geneva lock with the plate 117 ofsaid computing wheel next lower indenomination (Fig. 33). When, however, the'computing wheel 114-turns itszero to its sight-opening,

, a carry-over tooth 118 of the disk 117 fast to its computing wheel 114, vturns said carryover plate 120 through the position seen 1n Fig. 31 to the position 'een'in Fig, 32, wherd said. carry-over plate is heldagalnst further turning by means '0, a Geneva lock member 121 forming an extension of said carry-over plate which locks itself against the disk 117, as best seen' in Fig. 35. As will be seen in said Fig.,35,.the carr -over ,late 120. has been-turned so that it 1s held its Geneva lock memberl 121, and said. eneva lock member is locked against the disk 117-of the lower in denomination carry-'over plate'120V has moved the inclined computing wheel 114 in the foreground, while the carr .-over plate 120 is holding the'pawl 126 o the intermediate wheel 100, which intermediate .wheel engages the co'mputin wheel 114 seen in the background in said figure. ,Thus, .the carry-over late 120 .is locked against the computing w eel seen in the foreground, and thereby controls the computing wheel seen in'the background'. To put .it another' way,'the computing wheel by its'carry-over plate' controls the computing wheel next igher in denomination. vyIt will be seen that this turning of the cam 124from the position seen in Fig.` 33

f to the position seen in Fig. 32. Theresult of this is that the pawl 126 is held in the pafh of its lug 129 longer in said Fig. 33 than it is in Fig. 32, and therefore. the 'intermediate wheel carrying said pawlA and computing wheel driven thereby areboth turned one unit spacel further under the colnditions' shown in Fig. 32 than they are in Fig. 33.

lIn or ,stroke l carries al pin 188, said pin striking against- .the uppler side of the bell crank arm 186, s'o

In other words, the moving of said inclined cam 124 moves the computing wheel of higherdenomination one unit space further, therelymaking a carry-over on said wheel.

er to permit this Geneva carry-over operation to take-place, there is a cut-away portion219immediately adjoining each side of the carry-over tooth 118. From the above description, it will be seen that theT carryover'takes'place during the actual transfer the computing wheels` roper. When the turning o f the interme iate wheels v100 is rs from the intermediate Wheels to completed, each of said wheelswill display its zero through the .sight-opening 240.

The carry-over plates120 are positively returned to their normal positions (Figs. 30 and 33)" by the lugs 129, Awhich lugs, during the' depression of the adding key, rotate the l plates 99 around until said plates strike pins 123 4on the carry-over plates120, as seen in Fig..30. Said carry-over plates 120 are held against-,overthrow bymeans of a. stop-bar v220 against which they normally rest when -the 'mechanism is at rest. L

In addition to transferring numbersfrom the pin nest'133 tothe computin wheels pro r through the arms 102' and t 1e interme iate wheels 100, the adding key vis also' arranged to .restore the pins in the in nest all 133 to their normal position so that t e com- 'f uting mechanism may be s'et thereby to register another number. after the adding key lever 165has beendepressed and returned suiciently to operate Iall the intermediate wheels 100, it is carried up still farther so as to draw the pin nest 133 back from the position where it has been carried by the typewriter carriage to its normal position, as shown4 in Fig. 15. This is accomplished by means of a link 190 key lever 165, said link drawing downwardly a bell crank 189 pivoted at 187 s6 that an upwardly-extending arm 186 thereon will swing a hook 188 pivoted thereto to the eft. z v

On the return strokeof said adding key levez- 165, said hook 188 will catch on a pin 133l` fast on the pin nest 133 (Fig. 28), and draw said' pin nest back'to the position seen in Fig. 15. Said' hook188 is swung clear of thejgin' 1,33* at the veryfend of its return that w en said bell crank arm 186 is about For this purpose,

Said 'hook 188 is carried through a' guide late 221 which prevents it from falling beowthe pin 133 if said fpin is soine'distance to the left, assccn in Fig. 28.

lVhen said hook 188 has drawn the pin nest 133 to Aits normal position` seen in Fig.
